Influences of Teacher–Child Social Interactions on English Language Development in a Head Start Classroom     

Ruth Alfaro Piker  Lesley A. Rex 《Early Childhood Education Journal》2008,36(2):187-193

Increasing numbers of Spanish-speaking preschool children require attention to improve the likelihood of success in school. This study, part of a larger 2-year ethnographic study of a Head Start classroom, elaborates the role of teachers’ interactions with students who were learning English. Using an interactional ethnography approach, the authors focus on the social nature of these interactions. The study illuminates the kinds of teacher interactions with students that support and hinder the students’ language learning. It reinforces the importance of student engagement in social interactions with teachers and with English other than codes of obedience and authority. Finally, it recommends actions teachers can take to provide optimal circumstances for English learning interactions for students.

Contemporaneous and Longitudinal Associations of Sibling Conflict with Family Relationship Assessments and Family Discussions about Sibling Problems     

Gene H. Brody  Zolinda Stoneman  J. Kelly McCoy  Rex Forehand 《Child development》1992,63(2):391-400

The first purpose of this study was to examine contemporaneous and longitudinal associations of maternal and paternal measures of family functioning with observational and self-report assessments of sibling conflict. The second purpose was to determine whether the ways in which families attempt to solve siblings' problems are associated with contemporaneous and longitudinal assessment of sibling conflict. The results indicate that paternal equality of treatment and family harmony during family discussions about sibling problems, as well as parents' perceptions of family cohesiveness, are associated with lower sibling conflict levels.  相似文献   

Retraining chemistry teachers in the Philippines     

Mr Rex Kerrison 《Research in Science Education》1992,22(1):248-254

A recent large scale educational aid program to the Philippines included the retraining of secondary chemistry teachers. Teachers were introduced to new content and to alternative teaching strategies. An initial resistance to change arose as it was perceived that the new approaches did not take into account very limited school facilities and very large teaching groups. The lecturing style of teaching, which predominates at all levels throughout the country, was seen as the most effective method to handle overwhelming classroom problems. Resistance was overcome after alternative teaching styles were modelled. This paper gives an overview of the aid program and outlines the introduced teaching strategies. It contends that Asian teachers have been largely unaffected by western educational aid due in part to the fact that such aid is rarely accompanied by the modelling of introduced strategies. Specialisations: primary teacher education, primary mathematics, pre- and in-service science education.  相似文献   

US 2012 Live: when the classroom becomes a newsroom     

Mathew Charles  Ann Luce 《Cambridge Journal of Education》2016,46(1):113-130

In November 2012, 300 students came together in the Media School at Bournemouth University in the UK to report the US Presidential Election. Over the course of 10 days, students published 176 articles on a rolling news website, garnering more than 20,000 hits. On election night itself, students produced 10 h of live coverage on both TV and radio, airing 30 pre-recorded video packages and 35 pre-recorded radio packages. This experiential project adopted a so-called ‘live case’ methodology that encapsulated a high degree of application and a certain level of structure, which allowed for the ‘variety and uncertainty’ or reality to intervene. It also empowered and enabled students to reflect on and evaluate their individual experiences in light of their own learning styles. This paper will discuss the challenges and successes experienced during this experiential project, and will provide a nine-step guide on how others could replicate a similar project.  相似文献   

Transgenics in agriculture     

D. Rex Arunraj  B. Gajendra Babu 《Resonance》2001,6(2):83-92

Biotechnology has opened unprecedented avenues for exploring biological systems. One of the key techniques in genetic engineering is gene transfer, which involves transfer of recombinant DNA into plant cells to generate transgenic plants. Genes and genomes from a wide range of organisms are being manipulated for the benefit of mankind. Application of genetic engineering in agriculture has produced significant achievements such as yield improvement of major food crops.  相似文献

Aid effectiveness in education: Why it matters     

Desmond Bermingham  Olav Rex Christensen  Timo Casjen Mahn 《Prospects》2009,39(2):129-145

This article introduces the special issue of Prospects on “Aid effectiveness in education”. It brings together case studies of attempts in several very different contexts to improve the effectiveness of the use of aid in the education sector. By drawing on the historical evolution of the new paradigm over the last 20 years, the authors make the case for a closer focus on aid’s effectiveness in education, as well as the need to reform the aid effectiveness architecture. In particular, they identify two major obstacles that need to be overcome to improve aid’s effectiveness in education: the lack of sufficient institutional and staff incentives for coordinated and harmonized behaviour; and factors that lead to risk-aversion and discourage innovation in delivering aid effectively.  相似文献

A comparison of the agreement,internal consistency,and 2-day test stability of the InBody 720, GE iDXA,and BOD POD® gold standard for assessing body composition     

Bruce W Bailey  Gabrielle LeCheminant  Timothy Hope  Mathew Bell  Larry A Tucker 《Measurement in physical education and exercise science》2018,22(3):231-238

The study compared the agreement, internal consistency, and measurement stability of the GE iDXA, BOD POD, and InBody 720. Body composition of 43 men and 37 women (31.4 ± 10.7 years; 90% Caucasian and 10% other) was assessed in triplicate using each method over two different days. Mean percent body fat (% BF) of the participants was different for all three machines (27.6 ± 10.0% [GE iDXA)] 25.6 ± 10.4% [BOD POD], and 21.3 ± 10.6% [InBody 720]; p < .05). The coefficient of variation for same day repeated measures was 1.06% (GE iDXA), 3.29% (BOD POD), and 2.97% (InBody 720). The coefficient of variation for 2-day repeated measures was 1.81% (GE iDXA), 4.61% (BOD POD), and 4.24% (InBody 720). The difference between the GE iDXA and BOD POD was within acceptable variability, while the InBody 720 significantly underestimated % BF. The internal consistency was highest for the GE iDXA, followed by the InBody 720, and then the BOD POD.  相似文献
